WILLIAM J'. GRUBE, OF DELAWARE, OHIO.

LUBRICATING VEHICLE-HUBS.

Specification of Letters Patent.

Patented Mar. 1'7, 1914.

Application filed April 27, 1912. Serial No. 693,628.

The invention is embodied in the example herein shown and described, the features of novelty being pointed out in the appended claims. v

In the accompanying drawingsFigure 1 is a vertical sectional view taken longitudinally of the hub. Fig. 2 is a longitudinalsectional viewthrough the axle sleeve.

In the views 5 designates the axle sleeve, one end of which is provided with a fixed ball race or cone member 6 while the other is provided with a similar member 6 threaded thereon and a lock nut 7 for holding the same.

8 designates the hub shell and 9 a metallic spool shaped structure fitting on the axle sleeve within the hub shell and forming an annular oil chamber or reservoir. The heads of the reservoir member are provided with oil ducts 9 Arranged on the axle'sleeve within the hub and against the outer faces of the heads of the oil reservoir member are rings 10, 10 of absorbent materialfelt for example.

11, 11, designate ball cups fitting in enlarged portions of the hub and in the plane of the ball races.

12 designates the balls and 13, 13 are metal retainin rings fitting against the outer ends of t e cups.

14, 14, designate rings of felt placed against the ball retaining rings. Said rings 14, 14, extend into annular grooves in the race o cone members 6 and 6, as shown.

The characters 15, 15, designate dust caps threaded into the ends of the hub to hold the adjacent parts together.

The hub shell has an opening at 16 provlded with a screw cap 17, the lubricant being supplied to the reservoir through said opening. At 18 is a vent for letting out air when the lubricant is supplied through the openlng 16. The vent 18 is closed with a screw or threaded plug 19. q

The axle sleeve is provided with several short longitudinal grooves 5, 5 at the region of the absorbent rings 10, 10.

20 designate holes for the spokes of the wheel not shown.

In operation the oil passes from the reservoir through the ducts 9 into the absorbent rings 10, 10, and thence to the grooves 5 and thence to the bearings in both directions.

From the foregoing construction it is plain that dust has no access to the bearings and that a single filling of the reservoir will afford an ample supply of lubricant for a long time.

What I claim is;

1. Means for lubricating hubs comprising, in combination, a hub shell, an axle sleeve, a spool-shaped member forming in conjunction with the hub shell a lubricant reservoir between said hub shell and axle sleeve, and an absorbent member on the end of said sleeve beyond the head 9f the spool and externally of the lubricant chamber to take lubricant from the reservoir, said axle sleeve provided with a duct for taking lubricant from said absorbent member.

2. Means for lubricating hubs comprising, in combination, a hub shell, an axle sleeve, a headed spool-shaped member forming in conjunction with the hub shell a lubricant reservoir between said hub shell and the axle sleeve, a head of said spool-shaped member provided with an oil duct, and an absorbent member on the end of said sleeve beyond the head of the spool and externally of the lubricant chamber to take lubricant from the reservoir, said axle sleeve provided with a duct for taking lubricant from said absorbent member.

3. Means for lubricating hubs comprising,

in combination, a hub shell, an axle sleeve, a bricant from the reservoir, said axle sleeve spool-shaped member forming in conjuncprovided With a duct extending to the option with the hub shell a lubricant reservoir posite faces of said absorbent member.

between said hub shell and axle sleeve, and WILLIAM J. GRUBE. an absorbent member on the end of said Witnesses: sleeve beyond the head of the spool and ex- W. A. CAMTIGE,

ternally of the lubricant chamber to take lu BENJAMIN FINOKEL.
